UNISORB AK Fixator System

AK FIXATOR® SYSTEM
AK1
AK FIXATOR® DESCRIPTION
UNISORB ®'S Model AKII Agile
Fixator® Mount has been developed
specifically to meet industry's demand
for a cost effective, truly "agile," machinery installation system.
The AKII Agile Fixator® Mount is
intended for use in anchorless or anchored applications and offers the capability to be quickly converted from
one to the other without disturbing or
removing the machine base. The system can be used with resilient pads of
varying stiffness and thickness to produce the vibration isolation load deflection characteristics required by the
machine builder or user.
The AKII Agile Fixator® Mount's
basic design incorporates the wellproven adjusting mechanism and
clamping nut torque retention system
of the Fixator® into an updated overall
mount design that permits installation
in any of six fundamentally different
ways. (See Figures 1 thru 6 on pages
AK3-1, AK3-2 and AK3-3.)
●
The system may be easily converted to an anchored variation if required at a later date by the simple
application of one of the three available
anchoring techniques.
●
Pre-layout or core drilling is not
required as the anchor holes are simply drilled through the mount base after
installation. The use of the optional
toggle clamp permits this to be accomplished even when overhanging machine components prevent access to
the center or side anchor locations.
No special foundation requirements.
●
Final installation approach may
be determined on the job site.
The necessity for anchor layout
drawings is eliminated.
●
Core drilling is eliminated (unless preferred).
●
Anchored and non-anchored locations may be intermixed where
necessary and are served by the
same mounting system. Only one
system needs to be specified.

AK FIXATOR® INSTALLATION METHODS
Figure 1.
This method of installation simply sets
the AKII Agile Fixator® on the Opt. 'Y'
Resilient Pad. The pad has a coefficient of friction of approximately .70
which will quite effectively prevent the
Fixator® from walking. The pad is available in either a 2 mm or 6 mm thickness. The standard pad is supplied in
90 durometer, but different durometers
are available on a special order basis
(contact Unisorb Engineering). An Opt.
'STE' Hold Down Stud is used to secure the Fixator® to the machine foot.
This method should be used when
some degree of vibration isolation is
desired, and when extremely close tolerances are not a consideration.

Figure 2.
This method of installation utilizes
Unisorb® Adhesive V-100 Epoxy Grout
applied beneath the Fixator®. Please
note that a minimum thickness of .09"
is recommended. This method also
uses the Opt. 'STE' Hold Down Stud.
This stud is capable of stretching to
allow adjustment after the anchor nut is
tightened. This method provides a
simple and inexpensive, relatively secure installation without disturbing the
floor. Please note that this method
provides no option for vibration isolation.

AK FIXATOR® INSTALLATION METHODS

This method of installation utilizes four
(4) Unisorb® Capsule Anchors and Stud
Assemblies with two (2) located on
each side of the Fixator®. The anchors
may be installed after the Fixator® is in
place. See page AK4-6 for instructions
on installing these anchors. This method
also uses the Opt. 'STE' Hold Down
Stud, and may use either the Opt. 'Y'
Resilient Pad or the Adhesive V-100
Epoxy Grout beneath the Fixator®.

the Fixator®. The Toggle Clamp is held
down with two (2) Unisorb® Capsule
Anchors and Stud Assemblies, one
located on each side. See page AK4-6
for instructions on installing these anchors. This method also uses the Opt.

AK FIXATOR® INSTALLATION METHODS
Figure 5.
This method of installation utilizes a
single, center mounted Unisorb® Capsule Anchor and Stud Assembly to
securely fasten the Fixator® to the floor.
The Capsule Anchor and Stud Assembly may be installed either before or
after the Fixator® is in place. The recommended practice, however, is to
install the anchor prior to placing the
Fixator®. This installation method utilizes either the Opt. 'Y' Resilient Pad or
the Adhesive V-100 Epoxy Grout and
may be utilized only if access to the
center stud anchoring location is available.
FIGURE 5. CENTER CAPSULE ANCHOR STUD
Figure 6.
This method of installation utilizes a
single, center mounted Unisorb® Opt.
'WES' Anchor Hold Down Stud. This
stud is placed into a core drilled hole
and secured with either Unisorb® V-1
cementitious or Standard V-100 Epoxy
Grout. A Unisorb® 12" x 15" Grout
Form is used with this configuration.
This method provides the most secure
anchoring of all, and is recommended
when very close tolerances are required to be held, and when access to
the center anchoring location is available. Please note that this method provides no option for vibration isolation.

UNISORB® CAPSULE ANCHOR SYSTEMS
WITH STUD ASSEMBLY
The Unisorb ® Capsule Anchor with Stud Assembly
offers tremendous holding power which is stronger
than the concrete itself. A graded blend of quartz
agregate transfers the pullout forces into the concrete. Since there are no expansive forces from
the anchor systems, they can be placed near the
foundation edges, chip troughs, coolant trenches
or wireways. High anchor-to-concrete strengths
are developed which allow smaller anchor holes
and smaller studs to be used than is possible with
conventional expanding anchor type systems.

QUARTZ AGGREGATE
CATALYST
The Unisorb ® Capsule Anchor with Stud Assembly is a
superior method of heavy duty anchoring using a high
strength adhesive to retain a threaded rod and other
materials such as rebar, in concrete and other masonry
material. The system consists of a glass capsule containing the proper proportion of base resin, hardener
and aggregate for the anchor, appropriate length stud
with washer and nut, and a drive unit to allow the stud
to be installed with a standard hammer drill.
INSTALLATION INSTRUCTIONS
1. Drill a clearance hole for the insert using a rotary hammer drill
or core drilling equipment. Refer to the chart for proper
diameter and depth for each anchor size and standard stud
material (50,000 psi). Drill deeper holes when using high
tensile strength studs or when close to the foundation edge,
chip troughs or have extremely close spacing.

2. Thoroughly clean the holes. Excessive dust will reduce the
holding power of the anchor. For best results blow out the
concrete dust using compressed air or flush out with water.
The strength of the bond will not be affected by wet or damp
holes.
3. Insert the capsule anchor.

†ULTIMATE TENSILE LOAD TEST DATA
Test results using 4,000 PSI concrete are given as a guide only.
It is recommended that tests to simulate actual conditions be
carried out to determine the suitability of Capsule Anchors for
particular applications.
To order specify capsule, stud and drive unit.
4. Assemble the drive unit into the hammer drill. Thread the nut
onto the stud about one diameter and insert the stud into the
drive unit. The drive unit should shoulder on the nut for ease
of removal. Drive the point end into the capsule. This action
will break the glass tube and mix the components. Turn the
drill off immediately when the stud is fully inserted.
5. Allow the anchor to cure about 1 1/2 minutes without
disturbing the drive unit. Two or more drive units may be
convenient for larger jobs. Remove the drill unit by placing a
wrench on the drive unit and another on the nut. Loosen,
being careful not to disturb the stud. Allow the anchor to cure
for the minimum time before using.
